Answer:

Step-by-step explanation:

y = k*x                    This is the formula for a direct variation.

  • y = 20
  • x = 4                        Substitute these values into the direct variation

20 = 4 * k                        Divide by 4

20/4 = 4k/4

k = 5

Answer: the constant of variation is 5

For the function g(x) = x – 2x^2, find g (–3) + 13
svp [43]

Answer:

<h2>g( - 3) + 13 = - 2</h2>

Step-by-step explanation:

g(x) = x - 2x²

To find g( - 3) + 13 substitute the value of x that's - 3 into g(x) and add 13 to it

We have

g( - 3) + 13 = - 3 - 2(-3)² + 13

= -- 3 - 2(9) + 13

= 3 - 18 + 13

We have the final answer as

<h3>g( - 3) + 13 = - 2</h3>

Hope this helps you
